Abstract (en)

The invention relates to the registration of three-dimensional image data of an imaged object, in particular of pre-operatively taken 3D image data of a bone structure of a patient, with a set of two-dimensional projection images of the object. The three-dimensional image data of the imaged object (16) comprise at least a first rigid part (21a) and a second rigid part (21b), wherein the first and the second rigid parts are movably connected to each other. The three-dimensional image data represent a region of the imaged object (16) containing the first rigid part (21a) and the second rigid part while the first and the second rigid parts are in a first state of position and orientation relative to each other. Sub-regions corresponding to the first and second rigid parts within the three-dimensional image data are identified and the three-dimensional image data are divided into at least first image data of a first sub-region representing the first rigid part (21a) and second image data of a second sub-region representing the second rigid part. A set of two-dimensional projection images of the imaged object (16) (and e.g. taken by imaging device 14) comprises at least one image taken in a first projection direction and at least one image taken in a second projection direction, the first and second projection directions being different projection directions. The set of two-dimensional projection images represents a region of the imaged object (16) containing the first rigid part (21a) and the second rigid part while the first and the second rigid parts are in a second state of position and orientation relative to each other. A processing device (19) registers the first image data of the first sub-region with the set of two-dimensional projection images thereby obtaining first registration information, and separately registers the second image data of the second sub-region with the set of two-dimensional projection images thereby obtaining second registration information. Then, the position and orientation of the first (21a) and second (21b) rigid parts relative to each other according to the second state using the first and the second registration information is determined.
